Information

This policy setting controls whether popups show during page unloading in Microsoft Edge.

The recommended state for this setting is: Disabled.

Rationale:

Allowing popups during page unloading can allow a page with a vulnerability to exhaust system resources through popups or introduce malware onto the system if clicked.

Impact:

None - this is the default behavior.

Solution

To establish the recommended configuration via GP, set the following UI path to Disabled

Computer Configuration\Policies\Administrative Templates\Microsoft Edge\Allows a page to show popups during its unloading

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from Microsoft here.

Default Value:

Disabled.
